SOFA-BED.

To adi, zzz/1,0m, if may concern:

Be it known that we, G'Us'rAvE. HOLMES, AXEL G. Bos'rRoM, and JOHN M.BosTRoM, residing in Milwaukee, county of Milwaukee, and State ofWisconsin, have -invented new land useful Improvements in Sofa-Beds, of

which the following is a description, refer' ence bein had to theaccompanying drawings, whic are a part of this specification.

Thislinvention relates -to improvements in an article of householdfurniture commonly known asa fsofafbed, which principally is 'in theforni-of asofa, so. as ordinarilyto be used in that form, butwhich maybereadily converted into abed'f The inventioir is directed chiefly to thenovel structure ofthe auxiliary' bed-bottom and to themeansre'latedthereto wherebyitis snugly packedaway in the sofa when not in use andcan be-easily and quickly converte,

ed into a usable bed-bo1ttom, includingthe the bed-bottom in position.

The invention consists of the parts'and thcircombinations, as hereindescribed and' the thereunder folded and supported bed' bottoni. Fig. 3is a transverse section of the sola, showing the inner surface andconstruc tion of the arm or end of the sofa.

I In the drawings ther y is shown a sofa ,frame or body'consisting f aback A. and the arms or endsf'of the sofa B B. These/parts 'are of anysuitable size and form to make up a sofa frame or body like or similartothose in common use, the arms or ends -being rigid to the back,`making.a strong and durable frame I l or body of the sofa-bed. meansfor"properlysupporting` and securing The sofa-seat O is also of a form`in com;

. "mon use and consists of a rectangular frame vhaving thereon anupholstered Orother cover forming the 'seat' proper of the -part. Thisrectangularor box-like seat in this sofa-bed isinounted on the framepivotally, so that it is adapted to4 be turned overupside down, thepivotal support of the seat being at its respective ends and mediallyofits width.

Mounted on and secured lto sills 4' in the porting-'blocks 5, one ateach end of theA sofaframe, each of which blocks is provided with ahorizontally-disposed elongated slot' and with astud-pin 7 projectinglaterallyinwardly from one side of the block xat alittle distancefrom and advisablyabove the front end of the slot 6. The slot 6is-enlarged medially at 8 to provide a siiicient-aperture fortheinsertion and removal of a, pin With a head thereon to and from theslot, which head is too large to esca e from the slot otherwise thanthrough suc enlarged aperture. j

On the ends of the seat-frame there is a hinge-plate 9, secured to theseat-frame op posite and complementary to the sup ortingbIocks 5. Thishinge-plate is provi ed-with a headed pivotepin 10, which pin is adaptedto enterand lit inovably in the slot 6 in the block 5. Also thehinge-plate 9is provided` with acurved slot 11,eccentric to the pin 10,to receive movably IOO . therein thestud-'pin 7 of the block 5, wherebythe hinge-plate 9 when with the seat it is swung about the pivot-pin 10is caused to move laterally on the block, and at the same time thepivot-pin 10 slides in and longitudinally of the slot 6 in the block 5.By means of the pivot-pins 10 on the ends of the seat C, slidable in theslots 6 in the blocks 5, and the stud-pins 7 on the blocks 5, riding in.the eccentric slots 11, the sofa-seat may be turned upside down, andwhen so turned the seat' will be shifted toward the front of the sofafbody to the extent of the length of the-slots 6 The sofa-seat C isadvisably provided with legs 12, pivoted to that edge of the frame ofthe sofa-seat which is at the rear when the sofa-seat is in the positionshown in Figs. 1 and 2. These legs are so pivoted to the frame of theseat that when the seat is over` turned to the position shown in Fig. 4the legs are adapted to be swung down and their free ends to rest asfeet on the floor, whereby when the seat is in this position the thenfront edge of the seat is supported by the legs directly on the'iioor.These legs are folded up behind the frame when it is to be turned backto 'the form of a sofa-seat, as shown in Figs. land 2. Also theseat-frameis provided with locking devices, one on each end, Fig. 19,each consisting, preferably, of a catch 13, secured to the end of theframe and projecting slightly divergingly outwardly downwardly therefromand adapted to engage a complementary catch 14, fastened on the sill orarm of the frame or body of the sofa, the catch 14 being inclined toengage Awedgingly the diverging portion ofthe catch 13, whereby the twocatch members 13 and 14 interlock Wedginely and securely when the seatis employed as a sofa in the manner shown in Figs. 1 and 2.

In connection with the sofa-seat'C there is a bed-bottom, composed in ageneral way of sid and end rails and a spring-wire mattress,

which bed-bottom is in three sections or members-an inner section 15, anintermediate or medial section 16, and an outer section 17. Thetransverse end rails of these inner and outer sections are hinged to theend rails of the medial section in the manner shown best in Figs. 2, 4,and 7, the rails being of angle-bai' and the vertical flanges of therails of the set-l ions l5 and I7 being made to and unfolding of thesections of the bed-bot' overlap the vertical flange of the rails of the1 tom. When the'bed-bottom is folded up in sections 16 and being hingedthereto by pivot-pins 18.' The horizontal anges -of these thus-hingedrails are cut away near the endsof the rails to permit of theoverlapping and fitting close together of the fiat sides of the verticaliiangesA at and adjacent to the pivot, and the vertical angesof therails of sections 15, 17, andv 19 severally project rearwardlyunderneath and fit upwardly against the horizontal flange of the railsof the thereto-hinged section when the sections are unfolded andextended in the same horizon- A tal plane in the manner shown in Fig. 4.This construction strengthens the structure and assists in preventingthe sections 15 and- 17 from tilting downwardly out of the plane of thesection 16 when the bed-bottom is extended. The section 16 is pivoted ateach end on legs 20, secured rigidly to the frame of the seat C in suchmanner that thesection- 16 can be swung to the horizontal position withrference tothe legs 20 when in an upright position, as shown in Fig. 4,or can be swung Ito a vertical position 1n the manner shown 1n Fig. 2when the bed-bottom is folded up with reference to the sofa-seat C. Alsofolding legs 21, one at -each end of the bed, are pivoted at one end tothe end rails of the section 15V and to the ends of the frame of thesofaseat C at their other endswhereby the bedbottoin is braced and heldin position with reference to the sofa-seat at the inner end of thebed-bottom when extended in the manner shown in Fig. 4 and is drawn upto and held against the under side of the sofa-seat frame when thebed-bottom is folded up in the man- A The outer section 17 of Y I shownin Figs. 4 and 6, but permitting the leg to be folded up behind the railwhen the bed is to be folded up in the manner shown in Fig. 2. v

The bed-bottom may be provided with a flexible wire mattress of anycharac ter adapted to serve as a mattress and at the same time to permitof the folding up of the sections; but preferably a mattress is providedwhich consists of a series ofparallel longitudi-..

nal wires 24, stretched fromend rail to end rail of the sofa-sections,with transverse conneetingwires 25,*the connecting-wires being bentaround the longitudinal wires, whereby they are held thereto and atthcsame time have such movement as permits of the folding up the mannershown in Fig'. 2, the buttons 26,

pivoted and swiveling on the edge of the.

outer rail ofthe outer bed-section 17, extend inone direction across theinfolded legs 22 and in the other direction extend to and receive theheaded pins 27 in recessesA therein,

whereby the buttons 26 serve as latches, se-v curing the section 17 vinplace detachabl)T with reference to the sofa-seat by their engagementwith the pins 27, which are fixed in thev lower edge of the apron 28 ofthe sofaseat, as'well as incidentally holding the fold"-l ed legs 22 inplace. y i

It will be observed that when the structure is folded up and in thecondition for use as a sofa, as shown'inFigs. 1' and 2, that the innersection of the bed-betteln is held close to andA practically againsttheunder side-of the which is utilized for holding ynbedclothes.-

frame of the sofa-seat andthlat the outer section 17 of the bed-bottomis locatedat a dis.- tance below the section 15,'thus providing a' spaceor receptacle D between these sections,

The bed is made up on the ,bottom and is folded up in this space at thetime of -folding up the bed-bottom and before the sofa-seat," with thebed-bottom thereon and the bed therein,`are turned over from theposition `of the seat asshown in Fig. 4 to' the position shown in F ig.A2. Of course by= the reverse operation the bed isy opened out for use onthe extended bed-bo`ttom- It will be understood that because oftheconstruction of the bed-bottom, consisting ofthe leaf-like sections 15and 17, hinged to the intermediate sectionsV 16, which is pivoted.

medially on standards,'and because of the arrangement of thefolding legs21 the two leafl'ike sections landv 17 f the bed-bottom are heldapartwhenlthe bed-bottom is folded'up, thus forming the receptacle forthe bed. It

n will also be noted that in unfolding thebedbottom the swinging of thesections 1-7 and` 15 into horizontal positions asy illustrated in Figs.7 and 4 theV section 15 will be elevated' from its position as shown inFig. 2 by reason ofthe interlocking end of the rails of the sec-v -tionsat the locality of their hinges, as shown in Fig. 7 .in connection withthe elevatingeffect of the folding legs 21, caused by their being swungupwardly and rearwardly by Ithe unfolding of the sectionsto the positionshown in Fig. 4.

In Figs. 13, 14,v and 15 the bed-,bottom structure is shown in a changedor modified form. 1 In this formof structure the bed-bot tom section 17a is formed on and is rigid to the under surface of or islreally theframe of the sofa-seat C, and this bed-'bottom section 17 a, with thesofa-seat rigid thereto, is 'pivoted at its front edge totheintermediate bed-bottom section 16a, which intermediate section"ispivoted medially to the frame or bodyof the sofa, conveniently bymeans of ivot pins`29, and the section 15a of theb'e botj of the rail.

is pivoted to the other extremities of the rails of the intermediatesection 16, and the `other edge of the section 15a is supported byfolding legs 21a, pivoted toit and at their other extremities pivoted tothe body or frame of the sofa, conveniently to the rear legsthereof, asshown in Figs. 13 and 15. A

iexible apron 30, that may be of coarse cloth, is attached at onel edgeto the inner edge of section I5a and at the other edge to the rear wallof the back A of the sofa,

forming a iiexible closure across the space 1. f'between the section ofthe bed-bottomand thev wall o f the-back offthe.sofa. A similarflexible'apron 31 is V'attached `along its upper edge tothe front edgeofthe frame of the sofaseat' and along its lower edge' to' across bar ormember of the' body or frame of the sofa between the front legsthereof'. y

Inl Figs. 16', 171,' and 18 there is a leg 22a, havin a modified `meansvof attachment to' lthe e geA of thefse'ction 1.7,"which in many casesis preferable. 'to' the means shown in Figs.l 4 and 6;; having a. headon its outer end, isxinsertjedloosely through the leg cured rigidly ina'socket thereforin the .side
